New from Umicore Galvanotechnik is Palluna ACF-100, an ammonia- and chloride-free high-speed electrolyte for deposition of a bright palladium-nickel alloy without the equipment corrosion and odors associated with ammonia-containing chemistries. Designed for use in reel-to-reel plating and tab plater continuous processing lines, the system nominally deposits alloy coatings containing 80% palladium. Deposit composition is said to remain constant over the entire applicable current density range, and deposits are light, white and extremely ductile with ~5 % breaking elongation. The company says the process is very stable, with chemistry remaining within tolerance limits and providing stable metal deposition rates between 24 and 27 mg/A·min even above 10 metal turnovers.
